The Master Coach enables easy data transfer thanks to its Wi-Fi connection. There is no need to weigh yourself with your smartphone, as the transfer to your smartphone occurs automatically via the Wi-Fi connection. The Master Coach analyzes your weight, body mass index (BMI), and body composition, including body fat, muscle mass, body water, and bone mass. This is useful for monitoring your weight. The data analysis is directly available in the Wellness Coach Health app, allowing for complete tracking of your weight. With each purchase of a Master Coach, you receive three months of weight loss coaching.
